Yes, and if they continue not to generate signals on low VHF, they will
continue not get any complaints.


But is is almost certain they they will claim success for their
"tests" in that "We got no complaints from low VHF users" when they
generated no such interference during testing-but are sure to when BPL
is widely implemented. That seems to make it very much necessary for
someone to document the parameters of what they DO generate so that
accurate information is available to challenge those later claims with
the facts when they make *inaccurate* reports of their of their
"successful" tests to FCC. It must be shown that the tests were
not properly done so as to actually test the system that will be
put into service.

That's a pretty substantial project-documenting the interference
generated at each -or at least certain critical- BPL test sites where
this could be the result. It then requires knowledge of local conditions
such as knowledge of what spectrum that is used locally by which users.

No wonder the BPL people are confident of a win. None of this is
accidental.


If they would reduce their emissions on the
ham bands to about 60 dB less than FCC, amateur radio wouldn't get a
significant amount of interference and ARRL could move on to new
challenges.


It's almost a certainty that the only way they will do that is if
they're challenged with collected data that causes FCC to require it.

If they were to do what it would take to reduce their emissions by 60 dB,
the system flat out won't work ... it only works passably as it is, which is
why they want to up the power. (A former user in the PPL trial area told
me - in front of the reporter - that when he had the system working (before
his service died and PPL couldn't/wouldn't fix it) he was getting "Maybe
4x dial-up speeds ..." He clearly wasn't impressed. Let's hope that there's
a lot of that going around. )
